My son in law picked up a 74 model just like yours at our favorite shop a couple days ago, for $199. It's missing the slide for the rear site, but we shot it once to see where it was hitting, about an inch low at 50 yards. If it wasn't missing the site part, I'd rate it at about 90% or so.
To add icing to the cake, after firing only one round thru it, it went to the woods today for it's maiden voyage, and it scored first time out. Then tenderloins sure was good for supper.
